Heart valve therapeutic device

Abstract

A heart valve therapeutic device (1) comprises a coaptation assist valve (20) comprising a conduit (2) with an outer surface (3) for coaption with the native leaflets, and a prosthetic flow valve (5) mounted within the conduit (2) to allow one-way flow through the conduit (2). Support for the coaptation assist valve (20) is provided by a support (10) for positioning the conduit (2) across the native leaflets, and connectors (15) attaching the conduit (2) to the support (10).

What is claimed: 
     
         1 . A heart valve therapeutic device for placement across a patient's native heart valve, the heart valve therapeutic device comprising:
 a support; and   a coaptation assist valve configured to reside across the native heart valve, the coaptation assist valve comprising:
 a proximal structural support coupled to the support via one or more proximal connectors, the proximal structural support comprising a first diameter; 
 a distal structural support coupled to the support via one or more distal connectors, the distal structural support comprising a second diameter; 
 a conduit coupled to and extending between the proximal and distal structural supports, the conduit configured to coapt with native leaflets of the native heart valve; and 
 a prosthetic valve mounted within a lumen of the conduit, 
   wherein the second diameter is smaller than the first diameter such that the conduit comprises a truncated cone shape.   
     
     
         2 . The heart valve therapeutic device of  claim 1 , wherein the support is configured to suspend the coaptation assist valve across the native heart valve without anchoring of the device to an annulus of the native heart valve or atrial or ventricular tissue adjacent to the native heart valve. 
     
     
         3 . The heart valve therapeutic device of  claim 1 , wherein the support comprises telescopic tubing for advancing or retracting the coaptation assist valve. 
     
     
         4 . The heart valve therapeutic device of  claim 1 , wherein the proximal structural support comprises a plurality of eyelets. 
     
     
         5 . The heart valve therapeutic device of  claim 1 , wherein the proximal structural support comprises a ring. 
     
     
         6 . The heart valve therapeutic device of  claim 1 , wherein the distal structural support comprises a ring. 
     
     
         7 . The heart valve therapeutic device of  claim 1 , wherein the proximal and distal structural supports are included in an integral frame. 
     
     
         8 . The heart valve therapeutic device of  claim 1 , wherein the one or more proximal connectors comprise one or more spokes extending at least partially radially to couple the proximal structural support to the support. 
     
     
         9 . The heart valve therapeutic device of  claim 8 , wherein the one or more spokes comprise a curved shape. 
     
     
         10 . The heart valve therapeutic device of  claim 8 , wherein the one or more proximal connectors comprise three spokes extending at least partially radially to couple the proximal structural support to the support. 
     
     
         11 . The heart valve therapeutic device of  claim 1 , wherein the one or more distal connectors comprise one or more spokes extending at least partially radially to couple the distal structural support to the support. 
     
     
         12 . The heart valve therapeutic device of  claim 11 , wherein the one or more spokes comprise a curved shape. 
     
     
         13 . The heart valve therapeutic device of  claim 11 , wherein the one or more distal connectors comprise three spokes extending at least partially radially to couple the distal structural support to the support. 
     
     
         14 . The heart valve therapeutic device of  claim 1 , wherein the conduit comprises a compliant surface for coapting with the native leaflets of the native heart valve. 
     
     
         15 . The heart valve therapeutic device of  claim 1 , wherein the prosthetic valve is configured to allow blood flow through the lumen of the conduit substantially in one direction only. 
     
     
         16 . The heart valve therapeutic device of  claim 15 , wherein the prosthetic valve is configured to allow diastolic blood flow and to prevent systolic blood flow. 
     
     
         17 . The heart valve therapeutic device of  claim 1 , wherein the prosthetic valve is positioned adjacent a proximal end of the conduit. 
     
     
         18 . The heart valve therapeutic device of  claim 1 , wherein the prosthetic valve comprises a plurality of prosthetic leaflets. 
     
     
         19 . The heart valve therapeutic device of  claim 18 , wherein the plurality of prosthetic leaflets are cup-shaped. 
     
     
         20 . The heart valve therapeutic device of  claim 18 , wherein the plurality of prosthetic leaflets are shaped like native valve leaflets. 
     
     
         21 . The heart valve therapeutic device of  claim 18 , wherein the plurality of prosthetic leaflets comprises a same material as the conduit. 
     
     
         22 . The heart valve therapeutic device of  claim 1 , wherein the support comprises a guide tube and an elongate support rail disposed within the guide tube. 
     
     
         23 . The heart valve therapeutic device of  claim 1 , further comprising a stent coupled to the support, the stent configured to maintain the support in a position in the patient. 
     
     
         24 . The heart valve therapeutic device of  claim 23 , wherein the stent is configured to be anchored within a superior vena cava.
